..The temporal dynamics of these complementary controls of visual and non-visual cognitive attention support the continuous generation of smooth pursuit so that eye tracking of a moving target can be prompt and accurate...

Differential roles of low and high spatial frequency content in abnormal facial emotion perception in schizophrenia

..Based on neurophysiologic and brain lesion studies, a velocity discrimination deficit can implicate early-stage motion processing if it is contrast-dependent or late-stage motion processing if it is contrast-independent...

Visual and cognitive processing of face information in schizophrenia: detection, discrimination and working memory

..Furthermore, this result provides evidence that in the context of broadly distributed cortical dysfunction, the usual functional specificity of the cortex becomes modified, even across the domains of sensory and cognitive processing...

..Face detection was correlated strongly with contrast sensitivities, but only weakly with verbal IQ. The results suggest that face detection ability begins to reduce in early aging, and is associated with spatiotemporal visual processing...

..Higher levels of facial processing, such as recognition of the individuality and emotional expression of faces, are abnormal in schizophrenia. It is unknown, however, whether the visual detection of a face as face is impaired as well...

..The reduced sensitivity to visual feature manipulations suggests that the modulation of basic visual signals, often used for vivid and dynamic expressions in art, may be under-appreciated in schizophrenia...

..A similar motion-discrimination deficit in schizophrenia patients and aging normal adults suggests that the mechanisms underlying motion processing in schizophrenia and normal aging may be associated...

Altered 'three-flash' illusion in response to two light pulses in schizophrenia

..Hepatitis B virus (HBV) infection is one of the most important risk factors for hepatocellular carcinoma (HCC). The specific aim of this study is to assess the influence of HBV infection on familial aggregation of HCC...
